A new study has found that outdoor exposure to artificial light at night can increase the risk of developing diabetes, dubbed the “silent killer”, by 28%.
Chinese researchers have found that artificial nighttime lighting (AL) is associated with poor blood glucose control and an increased risk of diabetes, with more than 9 million cases in Chinese adults linked to night-time exposure to drugs.
Well-lit street lights, cars and shop windows have been found to be detrimental to health, and scientists say the results could make a difference for night shift workers.
“Although more than 80% of the world’s population is exposed to light pollution at night, more than 80% of the world’s population is still exposed to light pollution at night,” said study authors Dr. This issue has received limited attention from scientists until recently.”
New study published in Diabetologia (Journal of the European Association for the Study of Diabetes) [EASD]), data from the China Noncommunicable Disease Surveillance Survey, which includes a representative sample of the Chinese population as a whole, taken in 2010 at 162 locations across the country, with approximately 100,000 participants.
The researchers measured body weight and height, as well as blood samples to obtain fasting and postprandial glucose levels, as well as glycated hemoglobin (HbA1c), a form of glucose found in red blood cells that acts as a blood detector. sugar levels for eight days to 12 weeks prior to the examination.
The researchers found that those who had the most exposure to artificial LAN lighting at night had a 28% higher risk of developing diabetes.
Local network exposure at night is a widespread environmental risk factor in today’s society. The intensity of light pollution has increased in urban areas to such an extent that it affects not only residents of large cities, but also remote areas, such as suburbs and forest parks, which can be hundreds of kilometers from the light source.
The authors concluded that “Further studies that directly measure individual exposure to LAN are needed to confirm whether this is a causal relationship with diabetes.”
The Earth’s 24-hour cycle has resulted in most organisms, including mammals, having a 24-hour circadian rhythm that affects physical, mental, and behavioral changes that adapt instinctively to the natural sequence of light and dark.
Disruption of circadian rhythms has been associated with cognitive decline, sleep disturbances, mood disorders, and reduced levels of happiness.
